The Ware for December 2020 was an Intellivision game console by Mattel. It used the CP1610 CPU, whose architecture was based on the PDP-11, and it had a whole kilobyte of RAM! Congrats to Chris on nailing it rather quickly; e-mail me to claim your prize!

I’v never heard of this chip before, despite tinkering with a number of different chips – and PDP-11s – back then. Looks like the Intellivision was the only major platform using it. Too bad it couldn’t run actual PDP-11 software. DECs micro PDP-11 required four separate chips then.
There were no fewer than 4 LSI versions of the PDP-11. The simplest – the T-11 – was a single-chip device but had most limitations.
